Tulips also have six petals and have parallel vein structures. Animals and plants have evolved together, with animals acting as pollinators for plants.

Haploid spores nwhich are produced by meiosis, are tiny and easily carried by wind and water; seeds, which contain a diploid sporophyte embryo 2n and its initial nutrient supply, are comparatively large; both spores and seeds are resistant to extremes of the plant’s environment, e.

What Types of Plants Produce Seeds? About how many species of monocots are there?

With further research it became apparent that the materials were not simply wastes, but had a purpose—to ward off insect attacks, to stop herbivores from eating the plants, or as a response to bacterial and other pathogens. What type of environmental cues do plants wait for before germinating? What does cross-pollinate mean? Dispersal not only permits colonization of new areas by a species, but also prevents competition for water and minerals between parent and offspring at the home site.

Once they land on the flower they eat the plants nectar which is a sugary sticky substance. The egg is at the micropylar end of the ovule and is fertilized to become a diploid zygote. So, too, are the eudicots with their triaperturate pollen. Angiosperms produce a wide variety of vivid flowers that attract pollinators that will eventually fertilize the plant. Like the conifers, these plants do not depend on water for fertilization of gametes.

One of the advantage that angiosperms hold against gymnosperms is their reproduction. Home Bryophytes Pterophytes Coniferophyta Anthophyta.

These complex structures are produced by the sporophyte plants. Peace Lily’s have netted veins and clustered vascular tissue. What type of stem is capable of photosynthesis? Monocots have a large endosperm in the seeds, and the embryo sporophyte has one cotyledon ; in dicots the nutrients of the endosperm have been transferred into the two cotyledons of the embryo sporophyte.

What are the male and female gametophytes in angiosperms? There is a tiny flower hanging down and others clustered above it.

Daffodils are easily identified as monocots due to their 6 leaf petals. The molecular data indicate the seed plants most closely related to the angiosperms are the gnetophytes and bennettitaleans, divisiin, incidentally, is the same conclusion reached by some botanists using morphological and anatomical features 50 years divusion.
